A system to transport infant children is provided. The system includes a base, a chassis releasably coupled to the base, and an infant car seat releasably coupled to the combination of the chassis and the base. The infant car seat having a first handle operable in a first function to release the infant car seat from the combination of the chassis and the base. The chassis comprises a frame; a pair of rear legs pivotally coupled to the frame at a rear leg pivoting axis; and a pair of front legs, each front leg pivotally coupled to a respective rear leg at a front leg pivoting axis, wherein the rear legs and the front legs are retracted and proximate the frame in a first transport condition, and wherein the rear legs and the front legs are deployable away from the frame to a second transport condition.

In one example, a travel system has a child carriage and a child carrier that removably couples to the child carriage. The carriage has a frame and wheels attached thereto. The carrier has a frame or body that supports a child therein, a handle coupled to the frame or body, a handle rotation lock, and a handle extension lock. The handle extends, retracts, and rotates relative to the frame or body to different rotational positions. The handle rotation lock selectively locks the handle in each of the rotational positions, and the handle extension lock selective locks the handle in extended and retracted positions. The carrier can have (i) a rotation stop that selectively blocks rotation of the handle when the handle is extended and/or (ii) an extension stop that selectively blocks extension of the handle when the handle is in a position for hand carrying the carrier.

A multi child stroller includes a stroller frame and a first seat. The stroller frame has two sections adapted to fold and unfold relative to each other. The first seat is disposed on one of the two sections. The first seat includes a first seat unit and a seat back positioning member. The first seat unit has a sliding slot portion. The seat back positioning member is rotatably disposed on the stroller frame. The seat back positioning member includes a sliding bar adapted to slide inside the sliding slot portion, so as to switch the first seat unit into one of a first unfolding mode, a second unfolding mode and a folding mode.

In one example, a child carriage has a frame with wheels. The frame has a coupler that removably couples the child carriage to a child carrier, such as a seat or bassinet. The frame has first and second leg assemblies, each having a front leg and a rear leg that are pivotably coupled about a first axis. The first crosspiece extends between the front legs of the first and second leg assemblies, and the second crosspiece extends between the rear legs of the first and second leg assemblies. The carriage is devoid of any push handle that extends above the child carrier. The frame folds about (i) the first axis from an expanded configuration to a first folded configuration so as to align hinges of the first and second crosspieces along a second axis, and (ii) the second axis from the first folded configuration to a second folded configuration.

A child stroller includes a stroller frame and a first seat. The stroller frame has two sections capable of being folded and unfolded relative to each other. The first seat is disposed on one of the two sections in a detachable manner. The first seat includes a supporting unit and a first seat frame. The first seat frame is adapted to hold the supporting unit. The first seat frame includes a seat hub, an upper seat tube and a lower seat tube. The seat hub is disposed on the stroller frame. The upper seat tube is disposed on the seat hub, and the supporting unit is slidably disposed on the upper seat tube. The lower seat tube is disposed on the seat hub and detachably connected to the supporting unit.

A car seat and stroller combination system includes a pair of front legs and a pair of back legs. The front legs and the back legs are designed such that they fold in an accordion-style configuration. In the unfolded state, the front legs are toward a front side of the car seat and stroller combination system and the back legs are toward a back side of the car seat and stroller combination system. However, in the folded state, the front legs are toward the back side of the car seat and stroller combination system and the back legs are toward the front side of the car seat and stroller combination system. The car seat and stroller system includes a handle than can be rotated in multiple positions and telescoped in or out by actuating a same button.

In one example, an organizer removably couples to a handle of a child carrier. The organizer has a tray, a storage container, and a flexible material. The tray has an opening that extends into the tray's upper end towards the tray's lower end and that can receive an item for storage. The storage container is disposed below the tray and has an open upper end and a closed bottom end. The flexible material is coupled to the tray and the storage container. The organizer transitions between an expanded configuration in which the flexible material defines sides of the organizer between the tray and the storage container, and a compact configuration in which the tray and storage container are positioned closer to one another. In another example, the child carrier has a handle that extends and retracts and that prevents installation of the organizer when the handle is extended.
